DECARBONIZING TORCH.

Application filed April 5, 1921. Serial No. 458,754.

To all whom it may concern: 7 1

Be it known that I, REGNALD R. BEEZLEY, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented certain new and useful Improvements in D e c a r b 0 n i zin g Torches, of whichthe following is a specification.

This invention relates to torches, more particularly to that class ofoxygen carbon burning torches or tools adapted for use for removingcarbon deposits from engine cylinders and the like, and has for itsobject to provide a torch of such class in a manner as hereinafter setforth with means whereby a combustible mixture formed by the oxygensupplied to the combustion chamber mixing with the hydrogen particles inthe carbon, will be fired or combustion created until the carbon iscompletely burnt out, thereby overcoming the employment of the use ofmatches for combustion purposes thus avoiding the damage of fire both tothe car and to the operator of the torch.

A still further object of the invention'will be found to consist in adecarbonizing torch which is extremely simple in construction,consisting of comparatively few parts therefor inexpensive tomanufacture, practical and highly efficient in operation, and designedfor universal use in various arts thus constituting an important andhighly desirable instrument or tool.

WVith these objects in view and others which willbe manifest andsuggested as the purpose and nature of my invention are revealed in thefollowing specification and drawing wherein I have shown a preferredembodiment thereof,

Figure 1 is a perspective view showing the invention as connected to astationary gas tank.

Fig. 2 is a longitudinal sectional view of the igniter as applied to thetorch.

Fig. 3 is a sectional View taken on the line 3-3 of Fig. 2, and

Fig. 4 is a sectional elevation of a modified form of torch.

Referring now to the drawings, wherein like parts designatecorresponding parts throughout the specification, 5 designates astationary gas tank preferably for receiving oxygen under pressure beingprovided with the usual gage 6 and conduit 7 which may be of rubbertubing connected to a torch designated in its entirety by numeral 8.

A central iron gas chamber 9 which is threaded at its respective ends10, 11 has threaded thereon end caps 12, 13 which may be made of brassor similar material as is well understood. The cap 12 is provided with areduced neck 14 to receive the end of the tubing or conduit 7, said neckbeing threaded to receive a nipple 15 as clearly shown by Fig. 2 of thedrawing. The cap 13 above referred to is also provided with a reducedthreaded neck 16 for receiving a torch valve 17 for controlling thepassage of gas to the tubing or nozzle 18 which may be also threaded asat 19 to the said torch valve. The caps 12 and 13 are provided withflanges 20, to confine and retain a fiber housing 20' preferablyconstructed of insulating material and spaced somewhat from the chamber9, a choke coil 21 being wound about said chamber substantiallythroughout its length, one end of said coil being connected to aterminal screw 22, from which leads an electrical conductor 22 providedwith a spring clamp terminal 23 for connection with the positive side ofeither the storage battery or the starter switch (not shown), of themotor vehicle, or, any other positive terminal (not shown) that isaccessible. The opposite end of the coil 21, as at 21, is connected to abinding screw 25, which is carried by the fiber housing 20. Mounted onthe housing 20 and associated with the metallic cap 13 is a switchelement, consisting of a metallic resilient member 26 in electricalcontact with and connected to the binding screw 25. The forward end ofthe member 26 has a depending contact 26', as well as an upwardlyprojecting finger grip 27 to provide for the convenient shifting of theswitch element to contact withthe cap 13 for the purpose of closing anelectrical circuit for a purpose to be presently referred to. The gas oroxygen after it leaves the chamber .9 and is fed into the enginecylinder, mixes with the hydrogen particles in the carbon under suchconditions providing a combustible mixture, which when fired or whencombustion is created or formed, will burn out the carbon from theengine cylinder and after the carbon has been completely burned outcombustion will cease. The firing of the combustible mixture, or thecreating of combustion of the said mixture, is had by closing thecircuit through the medium of the contact 26 engaging the metallic cap13. In this connection, it will be pointed out that the current fiowsfrom the positive terminal through the spring clamp 23, conductor 22',terminal screw 22, coil 21, coil end 21, switch element which isdepressed to bring the contact 26 against the cap 13 through the switchelement, cap 13 to nozzle 18. The nozzle 18 is positioned against thepiston (not shown), Within the engine cylinder and as the nozzle ismoved on the piston to make a good contact, will produce a white arc,under such conditions firing the combustible mixture and the combustionwill be continued until the carbon is completely burned out. The currentbeing grounded through the piston, or if the nozzle 18 is moved incontact with the cylindrical Wall of the engine, the current will begrounded through said wall.

It will be readily observed that the torch is such as to be carried inthe hand of the operator and manipulated at will, the spring switchbeing so positioned as to be actuated by the thumb or finger to makecontact and complete the circuit for the purpose in tended By thisconstruction, danger of fire is eliminated since the novel and improveddevice dispenses with the use of matches and otherwise constitutes asafe and very convenient tool or instrument for use in proximity toinflammable material or gasoline for instance in automobile workespecially in the removing of carbon deposits from engine cylinders andthe like.

In the form of the invention shown by Fig. 4, I have provided a torch 28connected by a tubing or conduit 29 to an oxygen tank and provided alsowith a torch valve 30 for controlling the passage of oxygen to thetubing or nozzle 31 in the same manner as above illustrated. In thisinstance, there is provided an iron core 32 having a coil 33 wound aboutthe same throughout its length, one end 34 of said coil being connectedto ascrew post 35, the conductor 36 being provided with a clamp terminal(not shown) for the obvious purpose. The opposite terminal of the coil33 is also connected to a spring switch 37 which is also manuallyoperated to make contact with one of the metallic straps 38 whichretains the fabric housing 40 on the torch. In this form of theinvention, the fiber housing 40 which is preferably of insulatingmaterial is provided with end flanged caps 41 se-,

cured thereto in any well known manner thus constituting a housing forthe core and coil above referred to. In this form of the invention, thecurrent will flow from the spring terminal (not shown) through the coiland to the switch which when closed makes contact with one of the straps38-, the gas will pass through the tubing and torch valve 30 so thatwhen the tubing makes contact with the wall of the combustion chamber,for instance of an engine,

will produce an arc and the desired fusing or the creating of combustionof the combustible mixture, as hereinafter set forth, Within the saidcombustion chamber. It will of course be understood that the openings ateach end communicating with the pipe 20 are of reduced diameter limitingthe flow of gas through the tubing 18.

In the practical use and operation of the torch, when it is desired forinstance to remove the carbon deposits from the cylinder of anautomobile, the operator will first remove the torch plugs or sparkplugs and introduce the nozzle 18 into the combustion engine of thepressure adjusting valve in its proper position. The torch valve is thenopened allowing the oxygen to pass into the combustion chamber to admixwith the hydrogen particles of the carbon forming thereby a combustiblemixture, and at the same time that the switch is actuated by theoperator closing the circuit and the current will flow through theswitch and to the oxygen nozzle which when coming in contact with thepiston or wall of the combustion chamber will make an arc and fire orcreate the combustion of said mixture thereby burning out the carbonfrom the cylinder.

In the accompanying drawings, I have illustrated my invention embodiedin one form by way of example, and which in practice has been found tobe highly satisfactory in obtaining the desired results. It will beobvious however that other embodiments may be adopted and that variouschanges in the details of construction may be resorted to by thoseskilled in the art without departing from th spirit and scope of theinvention. It is furthermore understood that the invention is notnecessarily limited or restricted to the precise elements shown exceptin so far as such limitations are specified in the subject matter beingclaimed.

Having shown and described my invention, what I now claim as new anddesire to secure by Letters Patent of the U. S. is 1-- 1. A decarbonizintorch comprising a gas chamber adapted to communicate with the source ofsupply, a valve for controlling the gas from said chamber, a torchnozzle communicating with said chamber and controlled by said valve andadapted to ab 2 against the wall of an engine cylinder, or the pistonwithin such cylinder, and an electrical connection between said nozzleand the source of electrical supply and including a choke coil.
